Lazy devs is the most oft repeated catch phrase in online gaming forums. And over shit like "I can't believe this beautiful 60fps game occasionally drops frames" or "I can't believe this AAA game runs at sub HD."
Yup, you see that quite a bit on here.
Anyway, good article and while I've not seen some of the misconceptions, I have no doubt they exist and on the other hand, I have also seen quite a number of these, even here on GAF. Lazy Devs being the most repeated one.
The Bugs one is another I see a lot here. "How come no one caught this bug". There can be several reasons for that. One of them actually is "It was never found during QA" which is possible due to how complex some bugs can be. Certain things needed to be done exactly to make it happen. It's why during actual Alpha/beta tests (aka not stress tests), when bug reporting, many devs ask for specific info on how to replicate the problem because without that, they may not get the same problem or even get a different bug that they didn't see while trying to find your bug that you reported.
Of course on the flip side, some of the most common bugs that get found quite quickly, they may have indeed be caught but the decision maker (ie publisher or another suit) decides "it's not worth fixing just now, leave it for the day 1 patch/post release patch" (or something similar).
So saying "Incompetent/lazy/etc" QA is pretty ignorant but is thrown around a lot. Sometimes on here, sometimes on other forums or comment sections. It's a pretty ignorant statement to blame QA. If you're going to blame anyone for something that you believe should have been fixed, blame the suits who made the decision. (again most likely the publisher not being willing to delay the game to fix it or think it won't affect sales - I admit this might be me being ignorant but it's better than blaming the QA for something they don't have the power to fix)
The game development is easy one. While I haven't seen anyone outright say it, it does feel like the idea is there. You look on any game dev team recruitment forum and you do see people thinking they can do all these big ideas and are recruiting people to help them. Some of them are obviously impossible things for first timers (MMOs being the biggest offender) but try and explain the realities and you usually don't get anywhere. Others have ideas and try to recruit teams for making these ideas happen while they have no skills of their own apart from 'ideas'. (side note: I once saw someone advertise themselves as an ideas engineer. I'm pretty sure it was a troll but it was pretty funny how dedicated he was to calling himself that)
So yeah while I've seen nothing said 'outright', the inherent idea feels prevalent in many peoples heads.
The realistic graphics one, now that again I haven't seen outright "If this game had more realistic graphics, it would be so much better" but I have seen many people dismiss any game that either isn't 3D or the art style isn't realistic. That makes it seem like those people who say that think it being realistic will make it much better than if it wasn't realistic.
Of course for some people, they just prefer a more realistic and grounded art style but there are people who think realistic = better I'm sure.
Final one I'll touch on is the DLC is evil one. I am personally not a fan of DLC but I have grown to accept it (though I'll not touch DLC that I don't wish to support of course. Something everyone should do. If you don't want to support whatever that piece of DLC is, then don't buy it).
I am however glad that it keeps people from getting laid off because there is no other work for them to do. We see plenty of layouts from restructuring companies, downsizing, etc and from companies that have to shut down. Without DLC being there for people to work on, we might see even more stories of layouts but it's not because the company isn't doing well, it's because they have no more work for the developers to do.
Now while I haven't seen every misconception mentioned here (I mentioned the ones I've seen), I have no doubt they exist. Like someone else said, many of these people WORK in the industry and as someone who works in the industry, goes to events (both consumer events like EGX or PAX or industry events meant for building connections - including both first time or very new developers (who don't know the realities of development) along with seasoned veterans), and probably have friends who are jealous of them being in the industry. They are bound to hear far more misconceptions than people who sit at their computers and browse GAF/gaming news sites all day.
What may seem obvious to you is not to another. Remember that.
